Casio CQ-1 Diagnosis and Repair

I decided it was time to solve the problem with the Casio CQ-1 I was sent in. I didn't have a lot of hope, but it went better than I expected!

I'm really happy to have got this working! It's such a cool calculator and I felt bad letting it sit for so long. Well it's finally up and running again.

Here's the mail video where I was sent this in: https://www.youtube.com/watch?v=ZlNC4jIp6b0&index=2&list=PLJVwF78cppBgseTyHko16AAniEmblynqW
